### Question: Who is at highest risk for Color blindness ?
### Response: Men are at a higher risk for color blindness than women. As color blindness is commonly inherited in a X-linked recessive fashion, about 8 percent of males, but only 0.5 percent of females, are color blind in some way or another, whether it be one color, a color combination, or another mutation.   The reason males are at a greater risk of inheriting an X linked mutation is because males only have one X chromosome (XY, with the Y chromosome being significantly shorter than the X chromosome), and females have two (XX); if a woman inherits a normal X chromosome in addition to the one which carries the mutation, she will not display the mutation. Men do not have a second X chromosome to override the chromosome which carries the mutation. If 5% of variants of a given gene are defective, the probability of a single copy being defective is 5%, but the probability that two copies are both defective is 0.05 × 0.05 = 0.0025, or just 0.25%.
In addition to those who are genetically predisposed to color blindness, people who suffer from brain or retinal damage, or who take the drug hydroxychloroquine (Plaquenil), are at an increased risk of color blindness.
